ABSTRACT:
An arrangement for inserting a nozzle unit in a spinning device for spinning synthetic fibers has shafts extending through and movable relative to the opening of the device, means for detachably connecting the first end portion of the shafts to the nozzle unit, and drive means connected to the second end portion of the shafts and operative for pulling the latter. When the nozzle unit is connected to the shafts, and the latter are pulled by the drive means, the nozzle unit enters the opening of the device. The shafts may move vertically or along a curved trajectory. The connecting means may be formed as hooks pivotally connected to the first end portions of the shafts by hinges and engageable with loops mounted on the nozzle unit. Hollow beams filled with a heat-carrying agent are built in a body part of the device. Means for actuating the drive means are located outside the hollow beam, and preferably, below the same.
